Teeny Tiny Terminators

<< < (3/3)

lilshawn:
if i have to do tiny wires, and must crimp, i strip back about 2x what i need and fold it over then solder it, gives it some bulk to clamp onto.

i use the same method for the screw down terminal blocks

Really?  I also twist them.  I guess so they don't fray out when I insert them into a terminal or something (or just 'cause I'm anal retentive).  You are saying just leave them straight?  Interesting.  I may have to form a committee to discuss to debate taking this under advisement.   ;D

You need to leave them straight.
The easiest way to understand this is to look at how barrel pins are crimped.



If you leave them straight, then the crimp action allows the open ends of the barrel to separate the strands of wire into two parallel bunches and then compress them tightly to hold them.  The force is applied evenly along the length of the wire.

If you twist the wires, how can the ends of the pin separate the wire into two bunches?  It can't.
What happens is when the open ends of the barrel comes down on the wire, the sides of the barrel can act like knives and cut/break the strands of wire, weakening the crimp.

I've read some online help that says to "twist the wire" before crimping.  That's just plain wrong IMO.

Wires should be twisted together for wire nuts or for soldering.  Not for crimping.

I understand . I just learned what Ihave been doing wrong for many years now
